一种通过 MonkeyType + Pytest 来自动注解的方法(准确率不高，仍需要人工修改)

type-apply.py

```
python type-apply.py
```

import os
import subprocess

DIR = ""

for root, dirs, files in os.walk(DIR, topdown=False):
    for name in files:
        if not name.split(".")[-1] == "py" or name == "__init__.py":
            continue
        path = os.path.join(root, name)
        mod = path[:-3].replace("/", ".")[2:]

        cmd = f"monkeytype apply {mod}"
        print(f"\033[34m{cmd}\033[0m")
        p = subprocess.Popen(
            cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True
        )
        stdout, stderr = list(
            map(lambda s: s.decode("utf-8").strip(), p.communicate())
        )
        if len(stdout):
            print(f"\033[92m{stdout}\033[0m")
        if len(stderr):
            print(f"\033[31m{stderr}\033[0m")

type-gen.py

```
monkeytype run type-gen.py
```

import pytest

TEST_PATH = ""
rv = pytest.main([TEST_PATH, "--verbose"])
exit(rv)
